Cored Composite Beam Set

Composite materials with specific properties are common in many industries such as aerospace, automotive,sports and civil engineering. Cored composite materials are lightweight,stiff and strong. They have good fatigue and impact resistance. Their properties can be tailored to match the specific needs of end users by changing constituent material types and manufacturing parameters.

For cored composite materials, a variety of carbon fibre architectures can be obtained by sandwiching a lightweight material with a composite skin. This reduces weight and cost with only a small compromise on stiffness.

The combination of materials used results in a specific configuration of mechanical and performance properties of the resulting composites and determines the end use possibilities.

The beams in the TecQuipment Cored Composite Beam Set have been designed to introduce students to the properties of cored beams and their construction.

The beam types included in the basic kits are:

• Foam core beam with 3.2 mm thick foam layer

• Foam core beam with 3.8 mm thick foam layer

• Honeycomb core beam with 3.2 mm honeycomb layer

• Solid carbon composite beam

All beams are bonded with epoxy resin.
